Experiences from the Implementation and Use of Multimedia Synchronization Mechanisms

EUROPEAN TRANSACTIONS ON TELECOMMUNICATIONS, Issue 3 2000
Theodoros H. Bozios
This paper presents experiences from the implementation of Multimedia Synchronization Mechanisms related to the support of the many-to-one inter-media synchronization and describes the proposed Synchronization Architecture and its Design Objectives. The main goal of the communication system in the proposed architecture is to maintain the asynchrony levels between the media streams belonging in a Synchronization Group between the levels specitied by the Multimcdia Application. This is achieved through appropriate Synchronization Primitives related to the management and monitoring of the synchronization. The pilper emphasizes on the implementation issues and problems, and the solutions adopted. concluding to the lirst experiences from the use of the synchronization. [source]

Awakening dynamics via passive coupling and synchronization mechanism in oscillatory cellular neural/nonlinear networks

INTERNATIONAL JOURNAL OF CIRCUIT THEORY AND APPLICATIONS, Issue 5-6 2008
István Szatmári
Abstract We have studied synchronization mechanism in locally coupled nonlinear oscillators. Here, synchronization takes place by passive coupling based on a reaction,diffusion process. We will compare this mechanism with basic synchronization techniques, showing their similarities and specific properties. In addition to synchronization, passive and local coupling can also ,awaken' non-oscillating cell circuits and trigger oscillation, provided that cells are locally active. This result resembles Turing's and Smale's works showing that locally communicating simple elements can produce very different patterns even if separate elements do not show any activity. This property will be demonstrated for two second-order cells and also for a large ensemble of oscillatory cells. In latter case, the network of oscillatory cells exhibits very sophisticated spatio-temporal waves, e.g. spiral waves. Copyright © 2008 John Wiley & Sons, Ltd. [source]

Synchronization among neighbouring RNCs in a TD-CDMA mobile network

INTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS, Issue 5 2007
Yin-Fu Huang
Abstract In the paper, we use zone concepts, and also consider multiple-bunch in a TD-CDMA mobile network. In the multiple-bunch environment, we need a synchronization mechanism to avoid inter-RNC interferences. Here, we use an Informed-of message to transmit local resource allocation results to other neighbouring RNCs through a high-speed network. Thus, inter-RNC interferences can be avoided and the global resource allocation can be made with the message passing. Within the resource allocation algorithm, we also find maximal compatible cliques to achieve the best resource utilization, using the graph algorithm finding maximal cliques in graph theory. Through the simulation, we found that the SRU classification using Conservative strategy matching the SRU allocation using Aggressive strategy has the best performance among all combinations.
